In succession of terrestrial ecosystem, bryophytes, algae and lichens constitute the primary components. Not only phylogenetically but also physically they are related to each other, as they are also found in close association and intermixed with each other on same substratum. A chlorophycean alga Ulothrix zonata (Weber & Mohr) Kützing has been found growing as an epiphyte on moss Macromitrium sulcatum (Hook.) Brid.. The association is peculiar as the algal filaments form a close net over the surface of moss leaves and axis.

Bryoflora of Munsyari and Dharchula Tehsil of Pithoragarh, Uttarakhand, Western Himalayas, India
(2012)
Uttarakhand state of India comprises unique topographical conditions and hence is rich in bryophytes. In present work two Tehsils-Munsyari and Dharchula of Pithoragarh have been explored extensively to assess the bryophytic wealth of this district. A preliminary checklist has been prepared which revealed the occurrence of 51 taxa of bryophytes from this district.

Since the existence of Nilgiri hills, bryophyte- the miniatures of plant kingdom play an important and crucial role in the stabilization of Blue Mountains ecology. Unlike Himalayas, the landslides were rare in the area, but with the time and changing global environment it had become a common sight. Significantly ever increasing population and vehicular traffic is the prime reason for them, to cater the need, roads are periodically broadened by cutting road sides destroying the habitat as also the inhabiting species. Bryophytes, are efficient soil binders that regulate the soil moisture and provide substrate for future plant succession. The habitat loss and nudeness of substratum gives impetus to rapid soil erosion that further enhances the problem of their very survival. The present communication provides significance of these avascular cryptogams in environmental assessment, ecological balance and their role in decreasing the pore pressure to check land slides.
